' Specification of Letters Patent. Patented Sept. 10, 1918.

Application filed .T une 19, 1916. Serial No. 104,556.

To all 'whom t may concern.'

Be it known that I, HENRY RABINowITz,

'a citizen of the United States, residing at 705 Georgia Ave., Brooklyn, in the county of Kings and State of New York, have invented a new and useful Window, of which the following is a specification.

My invention consists in the novel features hereinafter more fully described.

The objects of my improvement are:

First: To produce a window, which can be cleaned from the inside, without any danger of falling out.

Second: To have said window weatherproof.

Third:V To have said window simple, durable and inexpensive. K f

Fourth: To allow an air space in the mid-` dle of the window, Y I y I attain these objects by the window, one form of which is illustrated in the accompanying drawings or by any mechanical equivalent` or obvious modification of the same within the scope of my invention.

Figure 1 is a vertical section on the line A-B of Fig. 2 except that the detail 19 is shown as a vertical section through G-D of Fig. 2. Y

Fig 2 is a horizontal section through E-F of Fig. v1.

'Fig'. 3 is a vertical section on the line I-J of Fig. 1; itis shown as broken in two places.

Fig. 4 is a vertical section on the continuation of the line A-B of Fig 2 through the other side of the window casing, showing the jamb 16 displaced. A

Fig. 5 is an elevation of one of the toggle joints shown in Figs. 1 and 4. j

Figs. 6 and 7 are vertical sections through the line K-L of Fig. 10, but showing one of the jambs 16 displaced. y

Fig. 8 is an elevation of the toggle joint 30d shown in Figs. 6 and 7.

Fig. 9 is a vertical'section through the line M-N of Fig. 10.

Fig. 10 is a horizontal section through y O-VP of Figs 6, 7 and 9. ,n

Fig. 11 is a side elevation ,of4v the key 60.`

Fig. 12 is a front view of the key-plate 58.

Similar numerals and letters refer to similar parts through the several views, as follows: l

11 and 12 are the outer walls of the window casing.

13 is the stationary jamb shown at the left in Fig. 1. A

14 is a detachable plate, covering an opening in the lower part of said jamb 13; this opening is provided for allowing the sash weights 27 and 27'a to be inserted into and removed from thechamber inclosed by the wall 11, jvamb 13 and the vertical covers34 and 35 shown in Fig. 2.

15 is the upper part ofthe jamb shown to the right of the window in Fig. 1, which part 15 is also shown as stationary. Y

16 is the lower part of the jarnb vshown to the rightl of the window in Fig, 1, which.

part 16 is shown in Fig. 5 as being movable; the lower end or bottom` of said movable jamb 16is adapted to slide in the cutout 17a of the sill 17 the upper end of said jamb 16 l has a sliding strip 32 connected thereto; both the jamb 16 and the sliding strip 32' are adapted to slide on the underside of the guide board 31, shown in Figs. 1, 4, 6 and 7 18 is a horizontal weather strip shown` in Figs. 4, 6 and 7. y

19, 19a 19h, 20, 20, 201and'20b are vertical weather strips; 19, 19a, 19b and V20a also 2Ob are stationary; 20 and 2()d arefmovable together with said jamb 16, to whichthey are attached.

21 is the upper top of theinnerpart of the window casing; 22 is the lower top; the former limits the upward motion of the inner window 'sash 24; the latter limits the upward motion of the outer window sash 23.

The relative positions of the tops 21 and 22 are most clearly shown in Fig. 3;V they are shown as placed at different elevations` for two reasons: first, to allow an air space Y in the middle part of the window when the inner sash 24 is moved upward and the outer sash 23 downward; second, to allow the.

outer sash 23 when in the lower position to be revolved on a vertical axis, as hereinafter described, and to clear the weather strip 1S below it and the bottom of the sash 24 above it.

are handles on said sashes 23 and 24 for revolving the same on a vertical axis into a position convenient for cleaning the panes 4T from the inside.

2G is the cord attached at one end thereof to the sliding member 40, hereinafter described, and at the other end to the sash weight 27.

26L is the cord attached at one end thereof to the sliding member 41, hereinafter described, and at the other end to the sash weight 27a.

28 and 28n are the pulleys for said cords 2G and 26a respectively.

29 are bearing plates shown in Figs. l and 4 as secured to the inner sides of said movable jamb 1G and said casing` 12, opposite each other.

30, 30 are toggle links shown in Fig. 5 as pivotally connected to each other by means ot' the spindles 50 and to said plates 29 by means ot the spindles 2QLL and 29".

rllhe spindle 29h is shown in Fig. 5 as having a square end, which is adapted to lit a suitable key.

lt is evident that when the pin 29D is turned in a certain direction, the toggle joint 30 will change its position from that shown in Fig. 1 to that shown in Fig. 4, thereby causing the movable jamb 1G with the weather strip 2O to slide away from the sashes 23 and 24 toward the casing 12; the

sashes 23 and 24 are in this way made to clear the Weather strip 20. instead of moving the full width of the jamb .16, shown in Figs. 1 and 4, which janib is similar to that shown in Fig. 10, any convenient part of it, with the weather strip 20 attached to it, may be moved.

33 is a connecting rod, shown in Figs. 1, 4, 6 and 7 as connecting' the upper and lower toggle joints, so that, by operating one of these toggle joints by means of a suitable key acting on the spindle 29b above described, the other toggle oint will move liliewise, thereby moving the plates secured to the jainb 1G in a parallel direction.

designates the bearing plate for supporting the pulley 28a.

3T, 3S and 3Q are vertical guides `for the sliding' members 4U and 4l, shown in Fig. 2; and located at the outer side of the hinge boxes 42, which are shown in Figs. 1 and 2 as inserted into the 'trame of each of the sashes and at one side thereof.

43v are the front and rear covers et said hinge boxes 42; they are shown in Fig. 2.

lVhen the Iiamb 16 with the weather strip 20 is made to clear the window sashes 23 To bring the other sash into a similar position, the lirst sash is pushed upward, thereby causing the corresponding sliding member 40 or 41 to slide upward until said irst sash clears the upper end of the morable jamb 1G; the other sash is then brought down opposite to said i'novable jamb 1G, and the operation above descrioed is repeated.

The cords 26 and 26 above described are fastened each at one end thereof to the corresponding sliding members 40 and 41, which are connected to the corresponding sashes 23 and 24 by means of extensible hinges and hinge boxes 42 above described.

The sashes 23 and 24 are provided at their upper sides with openings 24b and 24*L respectively, shown in Fig. 2, and extending some distance downwardly, to make room for the ends of said cords 26 and 26 and to pass the portions of the pulleys 28 and 28a, which project beyond the face of the j amb 13.

47 are the window panes, shown in crosssection in Figs. 2 and 3.

48 is a horizontal weather strip shown in Fig. 3 connected to the underside ot the lower top 49 is a horizontal groove, shown in Fig. 3 as located in the upper side of the sash 23 and adapted to t said weather strip 48.

50 is the vertical cover in the rear of the upper end of the space, in which the sash 24 may be moved.

lVhere two windows are situated close together with a narrow space between them l provide the arrangement shown in Figs. 6 and 7, whereby the saine set otl toggle joints made to operate alternately both jamhs 16 and weather .strips 20 and 2Od thereby clearing the sashes of both windows, and thereby saving the space, which would otherwise be necessary, if the arrangement shown in F ig. 1 were used for each oi' the two windows.

51 is a strip shown in Figs. 6 and 7 as secured to the sill 17 to limit the motion of either of the movable jambs 1G.

52 is a sliding strip shown in Figs. (3 and as secured to the upper end ot each of the movable jambs 16 and sliding on the underside of the guideboard 31; the strips 52 of Figs. Gand 7 are similar to the strip 32 of Fi 1.

Figs. 6 and 7 show the alternate positions of each of the opposite jambs 16, which are operated by means of the key 60, shown in Fig. 11, engaging the square end of each of the spindles 29h, above described.

To prevent any lateral and twisting strains on said movable jambs 16 from being producedY by the action of said key 60 on said spindles 29", I Vprovide the forks 53, which are shown in Figs. 6, 7 and 9, and the openings53c in the rear wall 54 of the toggle chamber, as shown in Fig. 9.

53a is a horizontal bar connected at one end thereof to said fork 53 and terminating at the other end in a short column 53b under said spindle 29", as shown in Fig. 9.

The bar 53a is shown in Fig. 9 as sliding in a guide 64 and is encompassed by a spring 63, which is shown as abutting at one end thereof against said column 53h and at the other end against said guide 6 4, which is secured to the j amb 16.

The spring 63 tends to keep the prongs of the fork 53 normally out of the openings 532; but, when the key 60 is applied to the spindle 29d, it rst pushes said column 53b inwardly against the pressure of said spring 63, thereby causing the prongs of the fork 53 to enter said openings 53", and thereby securing one of the jambs 16, which is to be kept stationary for the while, against any strains and motion.

The same operation is performed alter-4 nately on the fork slidably connected to the other jamb 16 by means of the guides 29c when the latter is to be kept stationary.

56 are a pair of vertical weather strips shown in Figs. 9 and 10 as secured each to one of the movable jambs 16.

57 are a pair of vertical weather strips shown in Fig..10 as secured to the edges of 'the front cover 55.

61 is a tooth on said key 60, shown in Fig. 11; it serves to prevent the key 60 from being disengaged from the square end of said spindle 29b by the pressure of the spring 63 against said column 53", shown in Fig. 9.

It is evident that where both jambs 16 are movable as in Figs. 6, 7 and 10, two spindles 29b are provided with square ends as shown in Fig. 8 in elevation; but Where One jamb only is movable, as in Figs. 1 and 4, only one spindle 29b is provided with a square end as shown in Fig. 5.

58 is a suitable key plate shown in Figs. 9 and 12; it has an opening 59 for said key 60 and a notch 59a for the tooth 61 of the key 60 to pass through.

60a is an opening in said key 60, which I opening fits the square end of said spindles 29".

62 is a handle for turning saidfkey 60.

65 is a trolley on the upper edge of each of thev sashes 23 and 24 to reduce friction in sliding the same.. l

I do not therefore restrict myself to the design of the details as shown in the drawings; but I intend to include also all mechanical equivalents and obvious modifica-- ings and an intermediate chamber, having movable side walls forming a portion of the jambs and carrying a portion of the weatherstrips, whereby said jamb sections may be moved alternately into and out of operative positions.

3. A window frame having a horizontally movable section, a toggle joint adapted toV move saidv section horizontally and a key for operating said toggle joint, said toggle `joint normally having its two links in a straight line, thereby preventing the moving of said section without applying said key to said toggle joint.

4. A window frame having a horizontally movable section, a toggle joint adapted to move said section horizontally without lifting the same, a key for operatin said toggle joint, said toggle joint norma ly having its two links in a straight line, thereby preventing the moving of said section without applying said key to said toggle joint, and a horizontal guide board at the upper end of said section, said guide-board being adapted to coperate with said toggle joint to prevent the lifting of said section while moving the same.

5. The combination of a window frame having a horizontally movable section, a pair of toggle joints adapted to move said section horizontally without lifting the same, a key adapted to be applied to one of the lateral pivots of one ofv said toggle joints, thereby simultaneously actuating both toggle joints, each of said toggle joints normally having its two links in a straight line, thereby preventing the moving of said section without applying said key to said toggle joint, and a rod connecting the central pivots of each of said toggle joints, said rod being adapted to facilitate the starting of the motion of said toggle joints when said key is applied.

6. A window frame having two sash opencombined with a meansings and an intermediate Chamber having movable side Walls forming` a portion of the jambs and carrying a portion of the Weatherstrips, a means, whereby said amb sections may be moved alternately into and out of operative positions, and a means for automatically looking each of the movable sections to the frame While moving the other see-tion.

7. A Window frame having two sash openings and an intermediate chamber, having movable side Walls, forming a portion of the jambe, and carrying a portion of the Weather strips, a means whereby said jamb sections may be moved alternately into and out of operative positions, and a means for locking each of the movable sections to the frame While n'ioving the other section, said looking means eon'lprising a suitable fork carried by each of said jamb sections, said fork being adapted to be projected into corresponding openings in said frame, thereby looking said jamb to said frame, and a means for lecrpin` said fork noi'- mally ont of said openings.
